Clade A3i
About clad A3i:
- Scientists have identified a distinct trait in the coronavirus found in the people infected in the country, mostly in the southern states of Tamil Nadu and Telangana.
- They have named this unique cluster of virus population as ‘Clade A3i’ .
Why in the news?
- Scientists at multiple Council of Scientific and Industrial Research (CSIR) laboratories have identified a coronavirus type that may be the second most prevalent in India and may comprise 3.5% of the genomes globally.
News in detail:
- Of 361 genomes analysed, 45% of them were A2a making it the most dominant coronavirus clade in India.
- The newly identified clade A3i, comprising 41% of those analysed, is the second most dominant clade.
- With the new clade, there are 11 SARS-CoV-2 types identified globally with at least six of them identified in India.
- According to scientific analysis, the A3i clade mutates slowly compared to the A2a which is often disadvantageous for the virus.
- So far, there is no evidence of whether A3i is more virulent that it’s linked to more deaths.

Significance of such classification:
- Classifications are useful in establishing whether
- certain strains are particularly virulent
- spread more easily
- how they are likely to evolve over time and
- whether some could be less vulnerable to certain kinds of vaccines.
